Nestled in the lush landscape, a modern reinterpretation of a once-fallen barn now features a charming guest cottage with stylish details and contemporary amenities. Situated along a narrow lot in Germantown, New York, the cottage completes a cluster of existing buildings, forming an intimate courtyard on one side. Steel effect folding patio doors fully open the living areas to the expansive fields and the Catskill Mountains beyond.
The homeowners, a young family with parents living abroad, envisioned a cozy yet modern ADU for extended stays. Designed by Lauren Cawse, AIA, architect and partner at The Art of Building, the year-round retreat draws inspiration from traditional local barns while embracing a seamless indoor-outdoor connection.
Captivating Guest Cottage Design Enhances the Senses with Steel Effect Folding Patio Doors
The modern ADU design started with the site itself. Positioned between residential and commercial neighbors, the elongated property required a careful balance of privacy and openness. Architect Lauren Cawse approached the layout by redefining the existing house and garage as the east and west sides of an outdoor room, with the new cottage forming its southern boundary. This arrangement created a clear courtyard near the main residence while directing the 800-square-foot guest house toward the open meadow and the distant Catskill Mountains.
“The unique character of the site and its history inspired the architectural direction,” says Cawse. “The intent was to create a secondary structure in the compound in clear contrast to the modern farmhouse style of the house and garage.”
A Barn-Inspired Exterior Adds Visual Flair
The exterior envelope evokes a traditional barn with a simple gable shape, weathered wood siding, cedar shingles, and a foundation veneer made of local fieldstone. A large sliding barn door adds a complementary feature to the courtyard-facing side, creating a dynamic opening that maintains uninterrupted views through the cottage to the meadow beyond.
Steel effect folding patio doors surrounding the structure add a modern touch of transparency, and simulated divided lites allow the contemporary glass wall systems to harmonize with the traditional elements of the modern ADU design.
“The goal was to fully open the living areas to the outdoors, framing views to the meadows and mountains,” says Cawse. “The positioning of the NanaWall systems frames the views and, when open, dissolves the boundary between inside and out.”
Interior Design That Mirrors Nature’s Tranquility
Inside, the design program features a simple layout with one bedroom, a full bath, a kitchenette, and a living area with a wood-burning stove. The interior, a collaboration between The Art of Building and the homeowners, is defined by an understated palette and tactile materials that reflect the natural setting. Color is introduced through the framed glass views on all sides of the structure. Reclaimed timber collar ties span the ceiling overhead, while stone surfaces and naturally patinated metal accents add quiet texture throughout.
Custom hand-painted Delft tiles along the kitchen backsplash add personal detail, and terra cotta flooring in the bathroom brings warmth and old-world charm. Soaring ceilings and abundant daylight create a peaceful play of light and shadow, shifting subtly with the seasons and emphasizing the cottage’s connection to the natural landscape outside.
Sleek Steel Effect Folding Patio Doors Elevate the Modern ADU Design Aesthetic
Three customized steel effect folding patio doors define the living space, each aligned to respond to a different edge of the site. The largest, spanning nearly 20 feet wide and just under eight feet tall, opens directly onto the stone patio, allowing the main gathering area to extend fully into the landscape. Along the side of the living room, a smaller 10-foot-wide system introduces more light and ventilation, nearly creating an open corner condition if not for the structural post that supports the façade and roofline.
At the rear, a fourth ten-foot-wide system features a French door swing panel configuration that opens toward the courtyard, strengthening the design connection to the main residence. All steel effect folding patio doors were specified with a low-maintenance, water-rated Performance Sill to safeguard against inclement weather while providing a seamless, barrier-free transition to the outdoor patio.
Unique Customizations for Visual Appeal and a Steel Effect
Each folding patio door system is configured to open outward, maximizing usable floor space in the compact interior and allowing furniture placement to remain uninterrupted. By stacking outward, the steel effect folding patio doors, specified in a SE Classic Bronze powder coat, ensure every inch of the cottage is optimized. Simulated divided lites create a consistent rhythm across windows and doors, maintaining alignment with the traditional barn-inspired exterior.
In the bedroom, a three-panel, 10-foot-wide system mirrors these customizations, matching the steel effect divided-lite pattern and outward-opening configuration, extending the indoor-outdoor connection while preserving visual continuity throughout the ADU.
“The divided lites were crucial to the architectural vision, and while budget prohibited a steel and glass system, NanaWall Systems’ thin frames provide the open and airy feeling we hoped to attain,” says Cawse. “Simulated divided lites transition the thoroughly modern element of the glass walls to remain in harmony with the otherwise traditional palette.”
Matching Windows and Doors: Create a Cohesive Design Program
Alongside the larger openings in the living areas and bedroom, a smaller 3-foot-tall NanaWall tilt turn window was added to the bathroom. This window-sized NanaWall system perfectly matches the divided lite panels and sleek frames of the steel effect folding patio doors, creating a cohesive modern ADU design throughout. The compact opening provides ventilation and natural light, enhancing the spa-like atmosphere along with natural stone flooring. The matching glass lines and sleek profiles of the NanaWall Generation 4 comprehensive product line further unify visual consistency, allowing each system to fit into the architectural style seamlessly.
“This project had three bifold glass walls, a pair of double French doors with sidelites, and a single tilt turn window,” says architect Lauren Cawse. “Being able to work with a single manufacturer provided aesthetic cohesiveness and simplified coordination.”
Sustainability Where It Matters Most
New York weather can vary from hot 85-degree summers to cold 26-degree winters. Creating an efficient living space was a primary goal. To achieve this, the design included Timber HP-insulated walls and floors with a heat pump system for effective heating and cooling. Additionally, the steel effect folding patio doors and windows were specified with double-glazed panels to ensure a tight building envelope.
Indoor-Outdoor Living Spaces for Relaxing and Entertaining
In-house landscape designer Liz Pulver worked closely with the team to conceive open-air spaces that enhanced the connection between inside and outside. To the south end of the lot, the landscape transitions into an “enhanced meadow,” allowing the cottage to feel embedded within the surrounding fields rather than set apart from them. A circular pool was designed to mimic a natural pond with a modest footprint. Around it, a minimalist fence and sunken stone ha-ha wall offer discreet safety for young children.
Limited space due to existing infrastructure and zoning setbacks left only a small footprint for the swimming pool, prompting the designer to propose a circular form that maximized the usable swimming area. “We felt that the perfect way to integrate a pool into the property and to honor the landscape would be to treat the pool as a piece of art itself,” says Pulver. “The result is a beautiful round pool that serves as both a functional retreat and a sculptural moment.”
Final Thoughts: A Barn-Inspired Design for Contemporary Living
This modern ADU design skillfully combines modern features with the enduring charm of traditional barns. The outcome is a welcoming living space that stands out amid a stunning landscape. Natural materials that mimic the beauty of the outdoors, expansive steel effect folding patio doors that fill the space with fresh air and natural light, and a restrained interior design work together to create an inviting retreat for everyday living, throughout the seasons.
“When entering the site, the cottage feels as though it was always there,” says Cawse. “It achieves its two opposing goals by creating a feeling of intimacy and enclosure near the house while also functioning as a threshold to the expansive fields and views beyond.”

Refined Continuity: Bridging Classical Architecture and Modern Living
This comprehensive remodel of a grand Cow Hollow residence reimagines a historically expressive envelope through a lens of contemporary livability, precision detailing, and material restraint. The design approach carefully balances the home’s classical proportions and ornamental heritage with a refined, modern sensibility—evident in the disciplined palette of warm neutrals, soft plasters, pale oak flooring, and tailored millwork. Circulation has been clarified and subtly expanded to enhance spatial flow, while openings are leveraged to capture light, garden outlooks, and distant water views. Throughout, architectural interventions are executed with a high level of craft, ensuring that new insertions—whether cabinetry, railings, or apertures—read as seamless continuations of the original structure rather than applied elements.
The kitchen serves as the operational and visual anchor of the home, conceived as a sculptural yet highly functional environment. Custom rift-cut cabinetry, softened through a desaturated finish, is paired with honed stone surfaces and integrated brass hardware to create a quiet, tactile richness. A monolithic island establishes a central gathering point, while perimeter work zones are carefully layered with concealed storage, integrated appliances, and open, backlit shelving that elevates everyday objects into curated displays. The adjacent bar and entertaining areas extend this language, reinforcing a cohesive hospitality-driven program. In parallel, the primary bathroom is designed as a serene, spa-like retreat, where bookmatched stone, frameless glass enclosures, and finely detailed metalwork converge. The composition prioritizes symmetry, clarity, and light—balancing generous volumes with intimate moments through integrated lighting, custom vanities, and a restrained material hierarchy.
The library and ancillary living spaces introduce a more intimate scale, anchored by bespoke built-ins that combine closed storage with illuminated display niches, creating depth and rhythm along the walls. Here, material transitions and furniture integration are handled with particular nuance, allowing the architecture to support both quiet retreat and social gathering. A continuous language of custom railings—executed in refined metal profiles—threads through the interior and extends outward, where the exterior gate and garden elements have been reinterpreted to align with the home’s renewed identity. The entry sequence is now defined by a calibrated interplay of solidity and transparency, with sculptural metalwork and landscape integration establishing a sense of arrival that is both secure and elegant. Collectively, the project reflects a holistic transformation—one that elevates performance, livability, and aesthetic clarity while preserving the inherent dignity of the original architecture.

Nestled in the lush landscape, a modern reinterpretation of a once-fallen barn now features a charming guest cottage with stylish details and contemporary amenities. Situated along a narrow lot in Germantown, New York, the cottage completes a cluster of existing buildings, forming an intimate courtyard on one side. Steel effect folding patio doors fully open the living areas to the expansive fields and the Catskill Mountains beyond.
The homeowners, a young family with parents living abroad, envisioned a cozy yet modern ADU for extended stays. Designed by Lauren Cawse, AIA, architect and partner at The Art of Building, the year-round retreat draws inspiration from traditional local barns while embracing a seamless indoor-outdoor connection.
Captivating Guest Cottage Design Enhances the Senses with Steel Effect Folding Patio Doors
The modern ADU design started with the site itself. Positioned between residential and commercial neighbors, the elongated property required a careful balance of privacy and openness. Architect Lauren Cawse approached the layout by redefining the existing house and garage as the east and west sides of an outdoor room, with the new cottage forming its southern boundary. This arrangement created a clear courtyard near the main residence while directing the 800-square-foot guest house toward the open meadow and the distant Catskill Mountains.
“The unique character of the site and its history inspired the architectural direction,” says Cawse. “The intent was to create a secondary structure in the compound in clear contrast to the modern farmhouse style of the house and garage.”
A Barn-Inspired Exterior Adds Visual Flair
The exterior envelope evokes a traditional barn with a simple gable shape, weathered wood siding, cedar shingles, and a foundation veneer made of local fieldstone. A large sliding barn door adds a complementary feature to the courtyard-facing side, creating a dynamic opening that maintains uninterrupted views through the cottage to the meadow beyond.
Steel effect folding patio doors surrounding the structure add a modern touch of transparency, and simulated divided lites allow the contemporary glass wall systems to harmonize with the traditional elements of the modern ADU design.
“The goal was to fully open the living areas to the outdoors, framing views to the meadows and mountains,” says Cawse. “The positioning of the NanaWall systems frames the views and, when open, dissolves the boundary between inside and out.”
Interior Design That Mirrors Nature’s Tranquility
Inside, the design program features a simple layout with one bedroom, a full bath, a kitchenette, and a living area with a wood-burning stove. The interior, a collaboration between The Art of Building and the homeowners, is defined by an understated palette and tactile materials that reflect the natural setting. Color is introduced through the framed glass views on all sides of the structure. Reclaimed timber collar ties span the ceiling overhead, while stone surfaces and naturally patinated metal accents add quiet texture throughout.
Custom hand-painted Delft tiles along the kitchen backsplash add personal detail, and terra cotta flooring in the bathroom brings warmth and old-world charm. Soaring ceilings and abundant daylight create a peaceful play of light and shadow, shifting subtly with the seasons and emphasizing the cottage’s connection to the natural landscape outside.
Sleek Steel Effect Folding Patio Doors Elevate the Modern ADU Design Aesthetic
Three customized steel effect folding patio doors define the living space, each aligned to respond to a different edge of the site. The largest, spanning nearly 20 feet wide and just under eight feet tall, opens directly onto the stone patio, allowing the main gathering area to extend fully into the landscape. Along the side of the living room, a smaller 10-foot-wide system introduces more light and ventilation, nearly creating an open corner condition if not for the structural post that supports the façade and roofline.
At the rear, a fourth ten-foot-wide system features a French door swing panel configuration that opens toward the courtyard, strengthening the design connection to the main residence. All steel effect folding patio doors were specified with a low-maintenance, water-rated Performance Sill to safeguard against inclement weather while providing a seamless, barrier-free transition to the outdoor patio.
Unique Customizations for Visual Appeal and a Steel Effect
Each folding patio door system is configured to open outward, maximizing usable floor space in the compact interior and allowing furniture placement to remain uninterrupted. By stacking outward, the steel effect folding patio doors, specified in a SE Classic Bronze powder coat, ensure every inch of the cottage is optimized. Simulated divided lites create a consistent rhythm across windows and doors, maintaining alignment with the traditional barn-inspired exterior.
In the bedroom, a three-panel, 10-foot-wide system mirrors these customizations, matching the steel effect divided-lite pattern and outward-opening configuration, extending the indoor-outdoor connection while preserving visual continuity throughout the ADU.
“The divided lites were crucial to the architectural vision, and while budget prohibited a steel and glass system, NanaWall Systems’ thin frames provide the open and airy feeling we hoped to attain,” says Cawse. “Simulated divided lites transition the thoroughly modern element of the glass walls to remain in harmony with the otherwise traditional palette.”
Matching Windows and Doors: Create a Cohesive Design Program
Alongside the larger openings in the living areas and bedroom, a smaller 3-foot-tall NanaWall tilt turn window was added to the bathroom. This window-sized NanaWall system perfectly matches the divided lite panels and sleek frames of the steel effect folding patio doors, creating a cohesive modern ADU design throughout. The compact opening provides ventilation and natural light, enhancing the spa-like atmosphere along with natural stone flooring. The matching glass lines and sleek profiles of the NanaWall Generation 4 comprehensive product line further unify visual consistency, allowing each system to fit into the architectural style seamlessly.
“This project had three bifold glass walls, a pair of double French doors with sidelites, and a single tilt turn window,” says architect Lauren Cawse. “Being able to work with a single manufacturer provided aesthetic cohesiveness and simplified coordination.”
Sustainability Where It Matters Most
New York weather can vary from hot 85-degree summers to cold 26-degree winters. Creating an efficient living space was a primary goal. To achieve this, the design included Timber HP-insulated walls and floors with a heat pump system for effective heating and cooling. Additionally, the steel effect folding patio doors and windows were specified with double-glazed panels to ensure a tight building envelope.
Indoor-Outdoor Living Spaces for Relaxing and Entertaining
In-house landscape designer Liz Pulver worked closely with the team to conceive open-air spaces that enhanced the connection between inside and outside. To the south end of the lot, the landscape transitions into an “enhanced meadow,” allowing the cottage to feel embedded within the surrounding fields rather than set apart from them. A circular pool was designed to mimic a natural pond with a modest footprint. Around it, a minimalist fence and sunken stone ha-ha wall offer discreet safety for young children.
Limited space due to existing infrastructure and zoning setbacks left only a small footprint for the swimming pool, prompting the designer to propose a circular form that maximized the usable swimming area. “We felt that the perfect way to integrate a pool into the property and to honor the landscape would be to treat the pool as a piece of art itself,” says Pulver. “The result is a beautiful round pool that serves as both a functional retreat and a sculptural moment.”
Final Thoughts: A Barn-Inspired Design for Contemporary Living
This modern ADU design skillfully combines modern features with the enduring charm of traditional barns. The outcome is a welcoming living space that stands out amid a stunning landscape. Natural materials that mimic the beauty of the outdoors, expansive steel effect folding patio doors that fill the space with fresh air and natural light, and a restrained interior design work together to create an inviting retreat for everyday living, throughout the seasons.
“When entering the site, the cottage feels as though it was always there,” says Cawse. “It achieves its two opposing goals by creating a feeling of intimacy and enclosure near the house while also functioning as a threshold to the expansive fields and views beyond.”

Refined Continuity: Bridging Classical Architecture and Modern Living
This comprehensive remodel of a grand Cow Hollow residence reimagines a historically expressive envelope through a lens of contemporary livability, precision detailing, and material restraint. The design approach carefully balances the home’s classical proportions and ornamental heritage with a refined, modern sensibility—evident in the disciplined palette of warm neutrals, soft plasters, pale oak flooring, and tailored millwork. Circulation has been clarified and subtly expanded to enhance spatial flow, while openings are leveraged to capture light, garden outlooks, and distant water views. Throughout, architectural interventions are executed with a high level of craft, ensuring that new insertions—whether cabinetry, railings, or apertures—read as seamless continuations of the original structure rather than applied elements.
The kitchen serves as the operational and visual anchor of the home, conceived as a sculptural yet highly functional environment. Custom rift-cut cabinetry, softened through a desaturated finish, is paired with honed stone surfaces and integrated brass hardware to create a quiet, tactile richness. A monolithic island establishes a central gathering point, while perimeter work zones are carefully layered with concealed storage, integrated appliances, and open, backlit shelving that elevates everyday objects into curated displays. The adjacent bar and entertaining areas extend this language, reinforcing a cohesive hospitality-driven program. In parallel, the primary bathroom is designed as a serene, spa-like retreat, where bookmatched stone, frameless glass enclosures, and finely detailed metalwork converge. The composition prioritizes symmetry, clarity, and light—balancing generous volumes with intimate moments through integrated lighting, custom vanities, and a restrained material hierarchy.
The library and ancillary living spaces introduce a more intimate scale, anchored by bespoke built-ins that combine closed storage with illuminated display niches, creating depth and rhythm along the walls. Here, material transitions and furniture integration are handled with particular nuance, allowing the architecture to support both quiet retreat and social gathering. A continuous language of custom railings—executed in refined metal profiles—threads through the interior and extends outward, where the exterior gate and garden elements have been reinterpreted to align with the home’s renewed identity. The entry sequence is now defined by a calibrated interplay of solidity and transparency, with sculptural metalwork and landscape integration establishing a sense of arrival that is both secure and elegant. Collectively, the project reflects a holistic transformation—one that elevates performance, livability, and aesthetic clarity while preserving the inherent dignity of the original architecture.

As the designer behind this master bathroom transformation, my mission was clear: to breathe new life into an outdated and dimly lit space while catering to my client's distinct desires. The project was marked by the client's unwavering commitment to enhancing functionality privacy and preserving the owner’s cherished MTI tub, all while adhering to the unalterable presence of existing windows.
FEATURES:
1. A glass pass-through between rooms allows natural light to flow freely, promoting a sense of openness.
2. The ceiling-mounted sliding glass door hardware elevates the shower experience with taller glass panels and effortless operation.
3. Accessibility and safety were paramount, resulting in a zero-entry shower, strategically placed grab bars, and an 'assist' TP holder.
4. To cater to varying preferences, a main showerhead and hand shower were accessible for standing and bench use.
5. A shared glass door between rooms eliminated the inconvenience of cumbersome door swings.
6. Privacy was enhanced through gradient glass etching, ensuring comfort and tranquility.
7. The digital shower system allowed for personalized controls, accommodating the unique preferences of the couple.
Creating a private bath around the existing MTI tub initially seemed insurmountable. However, innovative thinking led to a transformative solution. The drop-in tub was ingeniously converted into a free-standing tub with a narrow quartz deck adorned with a captivating mother-of-pearl mosaic tile surround. A floating walnut shelf at the tub's end introduced practicality and organic beauty.
Black plumbing fixtures were chosen to accentuate the mesmerizing depth of the mother-of-pearl mosaic tile. Horizontal book-matched walnut vanities introduced warmth and character, seamlessly connecting the interior to the outdoor view. The white quartz countertop is a refreshing contrast to the intricate finishes, lending a touch of sophistication. The ceiling light over the tub, akin to the icing on a cake, added a final note of elegance.
To meet the client's need for increased storage, the vanities have pullouts & roll-outs. These thoughtful additions ensured effortless access to personal care products. LED-lit medicine cabinets not only provided excellent lighting but also served as storage for everyday essentials. Vanity toe kick lighting is thoughtfully designed with a motion sensor at the entry, providing a guiding path to the water closet. Particularly valued during nighttime, this feature prevents unnecessary lights from illuminating, preserving the tranquility of those in bed.

The Harmonious Blending of Inside to Out with Wood Framed Patio Doors
By NanaWall Systems, September 3, 2025
Wood framed patio doors
Some homes are designed to impress from the outside. This one was reimagined to breathe from the inside out with wood framed patio doors. For a family of music lovers and outdoor enthusiasts, the goal was about connection. Connection to each other, to the seasons, to nature, to sound, and to their lush backyard space for daily life and family gatherings.
Designed by Jason Hanrahan of Mode Architects, the home features a thoughtfully placed NanaWall kitchen pass-through window and, later, wide bifold doors in the family sunroom. The design evolved in two phases to fit the family’s indoor-outdoor lifestyle perfectly. The result is a renovation defined by openness, light, and laid-back living.
A Home Shaped by Light, Music, Wood Framed Patio Doors, and a Pass-Through Window
Kitchen Renovation Opens Space to Light and Entertaining with a Pass-Through Window
During phase one of the renovation, the existing kitchen was reimagined to replace a restrictive floor plan and outdated appliances. Central to its new design is a three-panel NanaWall SL60 folding window system—sized at counter height to serve as a flexible pass-through window for alfresco dining and entertaining. Custom divided lites were added to complement the home’s existing window styles.
The window frames were finished in a warm, off-white on both interior and exterior, tying the kitchen seamlessly to the rest of the home and its façade. The result is a transitional space that connects the kitchen directly to the outdoor dining area, a seamless connection across spaces.
“The countertop-height NanaWall system made the kitchen fit better into the family’s lifestyle,” says Hanrahan. “It supports hosting and day-to-day use without turning the kitchen into a full opening.”
Designed for Living: Home Reimagined Around How the Family Connects
After phase one introduced a NanaWall pass-through window in the kitchen, making serving, conversation, and time outside effortless, the homeowners returned to MODE to reimagine their older sunroom. The goal: a living room and music lounge that could open completely to the backyard. The solution was incorporating a full-height, five-panel NW Clad 740 wood framed patio doors. The Generation 4 folding glass wall offered the slimmest aluminum clad frames available, and therefore, was the ideal solution to achieve seamless connectivity.
Outside, the frames were finished in a warm off-white to match the façade. Inside, solid wood frames seamlessly integrate with the mushroom wood paneling and millwork. The nearly 15-foot-wide system was customized with divided lites placed high up to add rhythm while preserving unobstructed views and keeping transitions seamless.
“We wanted to maximize the opening size,” says Jason. “Not just to maximize light, but literally the opening as well. The family sunroom space became more useful.”
A Living Sunroom That Folds Open to the Garden
MODE centered the second half of the home renovation on the family sunroom, featuring wood framed patio doors to create a seamless transition from the interior to the garden. It’s the difference between “a room with a view” and a room that becomes the view. With the nearly 8-foot-tall system open, music spills outside; with it closed, daylight, acoustics, and comfort remain finely tuned.
“You are sitting in the house with the family. The opening frames the view of the pond and the trees,” describes Architect Jason Hanrahan. “They liked how it connected them with their family when they were outside… it made it more cohesive.”
Choosing Materials that Reflect Nature and Serenity
According to the architect, the design aims to bring the outdoors in with an organic material approach. Inside, the room is wrapped in mushroom wood reclaimed boards, whose textured grain warms the acoustics and steadies the eye. Large-format tiles keep lines calm and maintenance easy.
Outside, a long concrete tread and natural stone hold the grade without hard edges. Nothing shouts; everything contributes to a single idea: bring the outdoors in and the indoors out.
Energy Efficiency Meets Everyday Living
The systems’ energy-efficient and performance engineering make the sunroom a four-season retreat. The architect chose NanaWall wood framed patio doors to maximize the existing exterior opening, provide intuitive and easy daily operation, and create a threshold that feels like part of the floor rather than a barrier. T hese are hallmarks of NanaWall wood framed patio doors: engineered for durability and frequent use, precision-gliding panels, and performance-tested.
To ensure year-round comfort, the NanaWall wood framed patio doors and pass-through window were specified with double glazed panels for optimal performance regardless of weather. Paired with the thermally broken Low Profile Saddle Sill, the bifold door not only offers energy efficiency but also a seamless, barefoot-friendly threshold to the outdoors.
Final Thoughts
From weeknight dinners to weekend music sessions, this is now a home that meets the family at the place they actually live, gather, and connect in. The kitchen pass-through window keeps everyday hosting effortless. The music room turns into a garden room in seconds, inviting breezes and conversation across one continuous plane.
Here, NanaWall wood framed patio doors added versatile usable square footage and extended the soul of the home outdoors. By focusing on how the family truly lives, this home now opens in all the right ways: to light, to laughter, to nature, and to each other.

Nestled in the lush landscape, a modern reinterpretation of a once-fallen barn now features a charming guest cottage with stylish details and contemporary amenities. Situated along a narrow lot in Germantown, New York, the cottage completes a cluster of existing buildings, forming an intimate courtyard on one side. Steel effect folding patio doors fully open the living areas to the expansive fields and the Catskill Mountains beyond.
The homeowners, a young family with parents living abroad, envisioned a cozy yet modern ADU for extended stays. Designed by Lauren Cawse, AIA, architect and partner at The Art of Building, the year-round retreat draws inspiration from traditional local barns while embracing a seamless indoor-outdoor connection.
Captivating Guest Cottage Design Enhances the Senses with Steel Effect Folding Patio Doors
The modern ADU design started with the site itself. Positioned between residential and commercial neighbors, the elongated property required a careful balance of privacy and openness. Architect Lauren Cawse approached the layout by redefining the existing house and garage as the east and west sides of an outdoor room, with the new cottage forming its southern boundary. This arrangement created a clear courtyard near the main residence while directing the 800-square-foot guest house toward the open meadow and the distant Catskill Mountains.
“The unique character of the site and its history inspired the architectural direction,” says Cawse. “The intent was to create a secondary structure in the compound in clear contrast to the modern farmhouse style of the house and garage.”
A Barn-Inspired Exterior Adds Visual Flair
The exterior envelope evokes a traditional barn with a simple gable shape, weathered wood siding, cedar shingles, and a foundation veneer made of local fieldstone. A large sliding barn door adds a complementary feature to the courtyard-facing side, creating a dynamic opening that maintains uninterrupted views through the cottage to the meadow beyond.
Steel effect folding patio doors surrounding the structure add a modern touch of transparency, and simulated divided lites allow the contemporary glass wall systems to harmonize with the traditional elements of the modern ADU design.
“The goal was to fully open the living areas to the outdoors, framing views to the meadows and mountains,” says Cawse. “The positioning of the NanaWall systems frames the views and, when open, dissolves the boundary between inside and out.”
Interior Design That Mirrors Nature’s Tranquility
Inside, the design program features a simple layout with one bedroom, a full bath, a kitchenette, and a living area with a wood-burning stove. The interior, a collaboration between The Art of Building and the homeowners, is defined by an understated palette and tactile materials that reflect the natural setting. Color is introduced through the framed glass views on all sides of the structure. Reclaimed timber collar ties span the ceiling overhead, while stone surfaces and naturally patinated metal accents add quiet texture throughout.
Custom hand-painted Delft tiles along the kitchen backsplash add personal detail, and terra cotta flooring in the bathroom brings warmth and old-world charm. Soaring ceilings and abundant daylight create a peaceful play of light and shadow, shifting subtly with the seasons and emphasizing the cottage’s connection to the natural landscape outside.
Sleek Steel Effect Folding Patio Doors Elevate the Modern ADU Design Aesthetic
Three customized steel effect folding patio doors define the living space, each aligned to respond to a different edge of the site. The largest, spanning nearly 20 feet wide and just under eight feet tall, opens directly onto the stone patio, allowing the main gathering area to extend fully into the landscape. Along the side of the living room, a smaller 10-foot-wide system introduces more light and ventilation, nearly creating an open corner condition if not for the structural post that supports the façade and roofline.
At the rear, a fourth ten-foot-wide system features a French door swing panel configuration that opens toward the courtyard, strengthening the design connection to the main residence. All steel effect folding patio doors were specified with a low-maintenance, water-rated Performance Sill to safeguard against inclement weather while providing a seamless, barrier-free transition to the outdoor patio.
Unique Customizations for Visual Appeal and a Steel Effect
Each folding patio door system is configured to open outward, maximizing usable floor space in the compact interior and allowing furniture placement to remain uninterrupted. By stacking outward, the steel effect folding patio doors, specified in a SE Classic Bronze powder coat, ensure every inch of the cottage is optimized. Simulated divided lites create a consistent rhythm across windows and doors, maintaining alignment with the traditional barn-inspired exterior.
In the bedroom, a three-panel, 10-foot-wide system mirrors these customizations, matching the steel effect divided-lite pattern and outward-opening configuration, extending the indoor-outdoor connection while preserving visual continuity throughout the ADU.
“The divided lites were crucial to the architectural vision, and while budget prohibited a steel and glass system, NanaWall Systems’ thin frames provide the open and airy feeling we hoped to attain,” says Cawse. “Simulated divided lites transition the thoroughly modern element of the glass walls to remain in harmony with the otherwise traditional palette.”
Matching Windows and Doors: Create a Cohesive Design Program
Alongside the larger openings in the living areas and bedroom, a smaller 3-foot-tall NanaWall tilt turn window was added to the bathroom. This window-sized NanaWall system perfectly matches the divided lite panels and sleek frames of the steel effect folding patio doors, creating a cohesive modern ADU design throughout. The compact opening provides ventilation and natural light, enhancing the spa-like atmosphere along with natural stone flooring. The matching glass lines and sleek profiles of the NanaWall Generation 4 comprehensive product line further unify visual consistency, allowing each system to fit into the architectural style seamlessly.
“This project had three bifold glass walls, a pair of double French doors with sidelites, and a single tilt turn window,” says architect Lauren Cawse. “Being able to work with a single manufacturer provided aesthetic cohesiveness and simplified coordination.”
Sustainability Where It Matters Most
New York weather can vary from hot 85-degree summers to cold 26-degree winters. Creating an efficient living space was a primary goal. To achieve this, the design included Timber HP-insulated walls and floors with a heat pump system for effective heating and cooling. Additionally, the steel effect folding patio doors and windows were specified with double-glazed panels to ensure a tight building envelope.
Indoor-Outdoor Living Spaces for Relaxing and Entertaining
In-house landscape designer Liz Pulver worked closely with the team to conceive open-air spaces that enhanced the connection between inside and outside. To the south end of the lot, the landscape transitions into an “enhanced meadow,” allowing the cottage to feel embedded within the surrounding fields rather than set apart from them. A circular pool was designed to mimic a natural pond with a modest footprint. Around it, a minimalist fence and sunken stone ha-ha wall offer discreet safety for young children.
Limited space due to existing infrastructure and zoning setbacks left only a small footprint for the swimming pool, prompting the designer to propose a circular form that maximized the usable swimming area. “We felt that the perfect way to integrate a pool into the property and to honor the landscape would be to treat the pool as a piece of art itself,” says Pulver. “The result is a beautiful round pool that serves as both a functional retreat and a sculptural moment.”
Final Thoughts: A Barn-Inspired Design for Contemporary Living
This modern ADU design skillfully combines modern features with the enduring charm of traditional barns. The outcome is a welcoming living space that stands out amid a stunning landscape. Natural materials that mimic the beauty of the outdoors, expansive steel effect folding patio doors that fill the space with fresh air and natural light, and a restrained interior design work together to create an inviting retreat for everyday living, throughout the seasons.
“When entering the site, the cottage feels as though it was always there,” says Cawse. “It achieves its two opposing goals by creating a feeling of intimacy and enclosure near the house while also functioning as a threshold to the expansive fields and views beyond.”

Refined Continuity: Bridging Classical Architecture and Modern Living
This comprehensive remodel of a grand Cow Hollow residence reimagines a historically expressive envelope through a lens of contemporary livability, precision detailing, and material restraint. The design approach carefully balances the home’s classical proportions and ornamental heritage with a refined, modern sensibility—evident in the disciplined palette of warm neutrals, soft plasters, pale oak flooring, and tailored millwork. Circulation has been clarified and subtly expanded to enhance spatial flow, while openings are leveraged to capture light, garden outlooks, and distant water views. Throughout, architectural interventions are executed with a high level of craft, ensuring that new insertions—whether cabinetry, railings, or apertures—read as seamless continuations of the original structure rather than applied elements.
The kitchen serves as the operational and visual anchor of the home, conceived as a sculptural yet highly functional environment. Custom rift-cut cabinetry, softened through a desaturated finish, is paired with honed stone surfaces and integrated brass hardware to create a quiet, tactile richness. A monolithic island establishes a central gathering point, while perimeter work zones are carefully layered with concealed storage, integrated appliances, and open, backlit shelving that elevates everyday objects into curated displays. The adjacent bar and entertaining areas extend this language, reinforcing a cohesive hospitality-driven program. In parallel, the primary bathroom is designed as a serene, spa-like retreat, where bookmatched stone, frameless glass enclosures, and finely detailed metalwork converge. The composition prioritizes symmetry, clarity, and light—balancing generous volumes with intimate moments through integrated lighting, custom vanities, and a restrained material hierarchy.
The library and ancillary living spaces introduce a more intimate scale, anchored by bespoke built-ins that combine closed storage with illuminated display niches, creating depth and rhythm along the walls. Here, material transitions and furniture integration are handled with particular nuance, allowing the architecture to support both quiet retreat and social gathering. A continuous language of custom railings—executed in refined metal profiles—threads through the interior and extends outward, where the exterior gate and garden elements have been reinterpreted to align with the home’s renewed identity. The entry sequence is now defined by a calibrated interplay of solidity and transparency, with sculptural metalwork and landscape integration establishing a sense of arrival that is both secure and elegant. Collectively, the project reflects a holistic transformation—one that elevates performance, livability, and aesthetic clarity while preserving the inherent dignity of the original architecture.
